MACHINE FOR SETTING UP WIRE-BOUND BARRELS.

Specification of Letters Patent.

Patented Feb. 13, 1919.

To all 'whom t may concern Be it known that we, EDWARD W. ROBIN- sON and CHARLES JEWELL ROBINSON, citizens of the United States, residing in Savannah, Georgia, have invented certain Improvements in Machines for Setting Up Wire- Bound Barrels, of which the following is a specification.

Our invention comprises a machine for setting-up, in barrel form, a wire-bound set of staves such, for instance, as that produced by the machine constituting` the subject of our application for patent filed of even date herewith, Serial No. 213,232.

In the accompanying drawings* Figure l is a side elevation of a machine constructed in accordance with our present invention, and showing in dot-and-dash lines theset of wire-bound staves upon which the machine is intended to act;

Fig. 2 is a side elevation illustrating the action of the machine upon the set of staves;

Fig. 3 is a view partly in end elevation and partly in transverse section on the line 3--2-3, Fig. 2;

Fig. 4 is a top view of part of the mechanism shown in Fig. 2;

Fig. 5 is a sectional view of the wirebound set of staves as it appears before the action of our present machine upon it, and

Fig. 6 is a sectional view of the wirebound set of staves in the barrel form in which they are set up by said machine.

In the machine constituting the subject of our co-pending application successive properly shaped staves are bound together by wires which cross between successive staves and are twisted together beyond the terminal staves of the set so as to hold the staves in proper close relation to one another.

When the set of wire bound staves is delivered from the machine whereby such binding is effected they are in the form of a coil, as shown in Fig. 5, and in order to complete the barrel it is necessary to first set up the staves in barrel form, as shown in Fig. 6, and then to unite the terminal staves of the set so as to retain them in this condition, and our present machine is intended to eifect such setting-up action. V

The machine comprises opposite heads l and 2 maintained in iiXed relation to one another by means of a longitudinal connecting beam 4C or the like. The head l carries a pair of spreaders 5 and 6, whose outer faces are shaped to accord with the desired contour of the inner face of the barrel and whose free ends are beveled as shown, respectively, at 5zt and 6a in Fig. 1. The spreaders are provided, respectively, with arms 5b and 6b which are pivotally mounted `on transverse shafts 7 carried by brackets 72 projecting from the head 1. y

Rotatably mounted in other brackets 8 which also project from the head 1 is a vertical shaft 9 to which are secured a pair of vertically spaced cams 10 and 11, the uppermost of these cams acting upon an arm l2 on the upper spreader 5 and the lowermost cam acting upon a similar arm 13 on the lower spreader 6, as shown in Figs. 1 and 2.

At the upper end of the shaft 9 is an arm 14 whereby said shaft may be readily turned in either direction, and the pivot shaft of the upper spreader 5 has thereon a weighted arm 15 which partially counterbalances the weight of said upper spreader 5, the normal tendency of the latter, however, being to assume the lowered or contracted position shown in Fig. l when the arm 12 is relieved from thepush of the upper cam 10, whereas the tendency of the lower spreader 6 is to assume the lowered or expanded position shown in Fig. 2 when relieved from the push 0f the lower cam 11 upon the arm 13 of said spreader 6. The cams 10 and 11 are so set on the shaft 9 that the same movement of the latter which relieves the arm 12 from the push of the upper cam 10 caused the lower' cam 11 to exert its push upon the arm 13, the movement of the shaft 9 in the opposite direction having the opposite result.

Mounted on opposite side braces 16 projecting inwardly from the head 1 is a ring 17 having a flaring mouth 17a.

The opposite head 2 of the machine has bearings 2O and 20a in which is free to slide, longitudinally, a shaft 21 which has mounted upon it oppositely facing cones 22 and 23, disposed in line horizontally with, but on opposite sides of the axis of, a transverse shaft 211, which is free to turn in bearings on the head 2 and is provided at one end with a disk 25, having a beveled face whose degree of bevel corresponds with that of the with the bevel face of the disk will cause the latter to rotate in one direction, while longitudinal movement ofthe shaft 21 so as to bring the cone 28 in driving contact with the beveled face of `the disk 25 will cause the latter to rotate in the opposite direction.

VLongitudinal movement of the shaft 21 is effected by backward orv forward movement of a treadle 26 carried by one end of a shaft 27 which is also provided with an arm 28 having` in it an inclined slot 29 (Fig. 3) which receives an anti-friction roller 30 projecting from a vertically guided rod 31 whose upper end is pivotally connected to one arm of a bell crank lever 32 pivotally mounted in a projecting bracket 33 on the bearingA 20, the other arm of said bell crank lever being forked, as shown in Fig. 3, to

' embrace a grooved collar 34 on the shaft 21,

said groove receiving pins projecting inwardly from the Vforked portion of the lever arm, asl also shown in Fig. 3. By proper movement of the treadle 26 therefore either of the cones 22 or 23 may be moved into driving contact with the beveled face of the disk 25 and the latter may therefore be rotated in either direction, as desired.

Secured to the shaft 24 is a spur pinion 35 which meshes with a spur wheel 36 on a shaft 37 `free to turn in bearings on the top of the head 2, and provided with a spurwheel 38 which meshes with teeth on the upper face of a `pusher bar 39, the latter being suitably guided longitudinally in the grooved top of the head 2 and carrying at its inner end a pusher head 40 with beveled face 40a, said head 40. carrying projecting arms 41 upon which is mounted a ring 42 with flaring mouth 43.

An arm 44 extends downwardly from the head 40 and carries a roller 45 which runs upon the top of the longitudinal beam 4, and thus serves to provide proper vertical support for the pusher head 40 in its longitudinal movements.

'Projecting inwardly from the head 2 of the machine on either or both sides of the same is a rod 4 6 which overlaps the head 40 when the latter is in the retracted position shown in Fig. 1.

In the operation of the bound set of staves in the form of a coil, as shown'in Fig. 5, is held by hand in the position shown by dot-and-dash lines in Fig. 1, land 4the pusher head40 and ring 42 are then advanced so as to cause the beveled face of the head 40Lto engage with one end of the coil and forcel the opposite end of the same onto the beveled faces 5a and 6a ofthe spreaders 5 and 6 while the latterare in the contracted position shown in Fig. l.V As the movement continues the coils open out, and if the staves 'have not assumed the circular relation Shown in Fg- 6 by the time the ends of; `the stares .have passed the beveled ends f machine the wire- V the spreaders 5 and 6 the latter are expanded, as shown in Fig. 2, so as to insure the circular disposition of the staves in barrel form with the adjoining edges of the terminal stares of the set in close relation to one another, as shown in Fig. 6. The terminal staves can then be held in such close relation by means of retainers, such for instance, as shown in application hitherto filed, the spreader serving as an anvil to turn back the points of the teeth of said retainers and thus cause them to engage with the inner faces of the staves.

The rings 17 and 42 serve to press upon the outer faces of the staves when the latter are in the position shown in Fig. 2, and thus prevent undue separation of the adjoining edges ofthe terminal staves, and if the circle of staves is unduly expanded before the ends of the staves reach the flaring mouth of the ring 17 such circle will be contracted to the desired extent by said flaring mouth before the ends of the staves enter the ring 17.

When the parts are in the position shown in \Fig. 2 the head 40 fits snugly to the inner faces of the staves and the ring 42 to the outer faces of the same, and when the head 40 and ring 42 are retracted, after the closing `of the spreaders, they carry the barrel wit 1 them, but, before they reach the point of full retraction, the rods 46 serve to push the barrel free from contact with the head and ring and thus permit it to fall from the machine.

The spreaders 5 and 6, pusher head 40 and rings 17 and 42 may be readily changed without affecting any other parts of the machine so as to adapt the latter for action upon barrels of different sizes.

We claim:

1. The eon'lbination, in a machine for expanding a coil of wire-bound staves into barrel form, of a spreader having beveled ends for entering one end of the stave coil and opening up said coil, and a pusher having a conical face for driving said coil over said spreader and opening up the opposite end of the coil.

2. The combination, in a machine for expanding a coil of wire-bound staves into barrel form, of a spreader having beveled ends for entering one end of the stave coil and opening up said coil, a pusher having a conical face for driving said coil over said spreader and opening up the opposite end of the coil, means for moving said pusher from and toward said spreader, and rings surrounding said spreader and pusher, the ring which surrounds the pusher being movable with the same from and toward the ring which surrounds the spreader, said rings serving to restrict the opening movement of the coil.

3. The combination, in a machine for setting-up wire-bound barrels, of a head having a beveled face for entering one end of a stave coil, means for advancing and retracting said head, a spreader having beveled faces for entering` the opposite end oit' the stave coil, and means for expanding and contracting said spreader'.
